Reality TV! in 1979! Albert Brooks co-wrote, directed and starred in his first feature. He was far better when put on a leash by James L. Brooks in Broadcast News. (The latter Brooks has a cameo here.) The premise is that a studio has funded him to spend a year filming a typical American family. After some Portal-esque testing, this leads him to buy a house in Phoenix, Arizona opposite the subjects and antics inevitably ensue. He gets off a few good one liners amongst the mostly bland scenarios, but as a critique of scientism, society's fascination with psychology, consumerism, etc. it was already stale. The ending goes as it must: set it all on fire.
Janet Maslin: Brooks "is never without his absolute insincerity and irrational good cheer." And that can be a bit of a grind.
